Open region BD player method

I know there are many players that support changing the active region on a Blu-ray player, and I know there are many ways to do this (I like the Sony IR code method because it gives me an excuse to drag out my Arduino ) I also know that these methods only allow one region code to be selected at a time; that is, these methods will only allow PSR20 to be set to 0b001, 0b010, or 0b100 (1=A, 2=B or 4=C).

My question is, does anyone have a software method or package to flash a Sony player's firmware so that all BD regions are open simultaneously? In other words, is there a software-only method to temporarily or semi-permanently change the player so that a read of PSR20 returns as value 0b111 or any other value that ANDs to 111?

I want to avoid any and all modchips, traces, and soldering. Those are fun with Arduino, but not with mass-produced SMT circuit boards.
